TopTech TT-FM-2025 TechPure TTFM2025 Air Filter 20x25x4 Top Tech OEM Cartridge 20 by 25 by 4 in Furnace MERV 11 for Carrier TT-MAC-2522 TT-MAC-2025

Fits. Works. No problem w seller or delivery. A bit pricey but good quality. Gotta be careful nowadays w your measurements. A 2 x 4 is not a 2 x 4 anymore, so it goes w many measured items these days. Pay attention to the numbers you need. Bought a pricey 5 pack of filters that weren’t as advertised or right size. Actual measurements can sometimes be different from those advertised. Big run around to try and replace / refund. So measure twice and check theirs to be sure you’re getting the correct filter. A quick click can make for a giant hassle sometimes.

I was getting desperate to find this filter. I noted the other filter needed an assembly and I did not want to take a chance on having a filter collapse on me and REALLY wanted to get the original FILTER that my HVAC technician installed with my NEW UNIT. I was delighted to find out that THIS filter is EXACTLY the same one when I took out the "OLD/ORIGINAL" filter! LITERALLY the same size, make, build, and the "font" on the box is the same!!! IT's a clone! It's working great! Easy to put in and the fit is EXACT! THANK GOD! Gonna order me another one or two!

Perfect fit.

This is the same model our installer used. Fits perfectly and catches a lot of debris. Super easy install.

Worked easily.

Got this filter to fit a newly installed TopTech 4" filter housing in my AC system. The ones from Honeywell are too wide and would not fit. These are top quality filters and just a good or better than what you find in the big box stores.

Pricey, but filter works good.
